does the rs tuner maps do something to the ecu to stop the emmissions light coming on?
before i had the rs tuner map done my light would come on all the time even with the cat on. i then decat it and it was on constantly.
i then had the rs tuner map done and havent ever seen the light again and this was almost a year ago.
